The correct answer is: A. Double Entry System.
A double-entry system is a system of accounting in which every financial transaction is recorded twice, once as a debit and once as a credit. This system is designed to ensure that all financial transactions are recorded accurately and that the accounting records are in balance.
A double-entry system is the most popular system of accounting used in public utility concerns because it is a comprehensive and accurate system that provides a clear picture of the financial position of the company.
A double account system is a system of accounting in which each account is recorded twice, once in a debit column and once in a credit column. This system is less accurate than a double-entry system because it does not provide a complete picture of the financial position of the company.
A single entry system is a system of accounting in which each transaction is recorded only once, in a single column. This system is the least accurate system of accounting and is not commonly used in public utility concerns.
A government accounting system is a system of accounting that is used by governments to track their financial transactions. This system is different from the systems used by businesses because it must comply with government regulations.
